The Post Office Annex development, as presented in a preliminary design by Brandywine Realty Trust, proposes two mixed-use towers fronting on Walnut and Chestnut Streets, and a 1667-car parking garage with street level retail in the middle of the block. The now complete Parking garage will soon host its first tenants, Old Nelson Food Market and the Schulykill River Development Corporation.
The Walnut Street Tower will offer 500,000 sf of office space, with Penn leasing 115,000 sf; 12,000 sf of retail and restaurant space; 200,000 sf for a 225 room Hotel; and a 125,000 sf, 50 unit condominiums. The Chestnut Street tower will provide 300,000 sf of apartments and 7,000 sf of possible retail along Chestnut Street.
